4' claim.A (c1. :is-4v) This invention relates to spectacles. It has for an object the provision of a`novel form of frame which can be clamped tightly about lenses even though there might be slight variations in the 5 sizes of the lenses, there being means for concealing any gaps which may be left in' the frame due to its application to lenses which are slightly oversize.

It is' a further object of the invention to provide a novel connection between the spectacle frame Aand the bows,'.said connection being such as to permit quick, minute adjustment of the bows upthe lower section can be of the usual clear un colored glass.

With the foregoing the other objects in view which will appear as the description proceeds, the invention consists o f certain novel details of con- A struction and combinations of parts hereinafter more fully described and pointed out in the claims,

it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed;

In the accompanyingI drawing the preferred form of the invention has been shown.VA

In said drawing Figure 1 is a rear elevation of the spectacles embodying the present improvements, the forked ends of the bows being shown in section.

Figure 2 is a plan view of the spectacles,'por tions of the bows being broken away.

Figure 3 is a front elevation of the front portion 40 of the spectacles. A

Figure 4 is a side elevation of the spectacles, the bows being broken away.

Figure 5vis a section on line 5-5, Figure 1, 'a portion of the-bow being illustrated in two positions by full and dotted lines respectively. Figure 6 is a perspective view of the forked end of one of the bows. l

Referring to the flguresby characters of reference, I designates the lens. frames formed ofany'A suitable'material and of any desired configuration. Each of. these frames is split at its inner side as shown at 2 and a lug isextended laterally .from the lframe at its upper end while another lug 4 is extended from the frame at its lower end, the lugs of each frame being extended toward the opposed frame and being of course located at the split or breakin the frame. Formed integral with the lower lug 4 4of each frame is a bridge 5 and the ends of the bridge are enlarged to provide shields 6 which not only extend in v:i front of the lugs 4 but also in front of land above the lugs 3. Nose pieces 1 are joined in any suitable manner to the respective frames below and adjacent to the bridge. l

'I'he two lugs ion each frame are joined by a l0 tightening screw 8. By turning this screw in one direction the lug 3 will be forced toward the lug 4 so that the frame I will thus be tightened about the lens L seated therein. Thus itwill be apparent that each frame can be used in connection l5 with lenses not only of correct sizes but also with lenses which are slightlyoversize and any gaps which might be left between the lugs 3 and 4 will not be objectionable because they will not be visible when the spectacles are viewed from/the 20 front. e

Each lens is preferably formed" of an upper section 9 formed of colored glass and a lower section I0 formed of clear 'or uncolored glass.` The two sections are fused together to form a one 25 piece lens and are adapted to be subsequently ground to meet the requirements of the user. By forming a lens in two pieces fused together one of which is colored, it becomes unnecessary to use separate colored glasses in frontof or in lieu of prescribed glasses. It has been found that where supplemental colored lenses .are used or colored shields are provided, adeection of the vlight rays occurs which is objectionable to persons required to use specially ground lenses.' The pres- 35 ent lenses will overcome these objections by providing ground lenses each ln one piece but having a colored area and a clear or uncolored area.

A compositelens such as described has been found particularly advantageous for use bythe 40 drivers of vehicles because it is' unnecessary to use separate sun-shields or colored lenses for excluding the blinding .rays of the sun.

For the purpose of connecting the bows to the frames I anovel form of joint has been provided. 45 'Ihis includes a clip-like member II fastened in any suitable manner to the ,outerlside of each framel I and formed with upper and lower ears I2 and I3 respectively. lEach of these ears is in the nature of a channel open at its inner side 50 and at that end remote from the frame I. A) pivot'pin I4 is extended through both channelled' ears andengages the upper and lower fingers I5 and I6 of thev forked end of a. bow I'I. The upper finger I5 of each bow can be extended straight 55 forwardlyirnthebowasshownwhilethe lower nnger I l is preferably parallel with nnger I5 but extended from a downwardly oiiset por` positions as in F'igure 4 and as shown by fll lines in Figure 5, the bow will be extended at right angles to the plane occupied by its frame I. However by bending the oiiset I8 backwardly away from the frame l linger II will be slightly elongated so that the bow I1 will be brought to an upwardly inclined position as indicated by broken lines in Figure 5. By bending the odset I l in the opposite direction the bow will be brought to a downwardly inclined position. Thus the angle of the frame i relative to the bows can be readily changed-to meet the requirements and without the danger of breaking the lens as irequently happens when an attempt is made to bend the ordinary bow close to its pivotal point.

By providing channelled ears I2 and Il the intermediate portions I9 thereof will act as stops for limiting the movement of the bows away from eachtother'. This will be apparent by referring to Figure 2.

While it is preferred to make the lenses by fusing the two sections of glass together it is to be imderstood that these sections can be joined with cement or in any other suitable manner.

Winti;` is claimed is: l

l. Spectacles including lens frames split at their inner sides, a bridge connected to the frames accusa below the split. said bridge including end shields, and means back oi' the shields and concealed thereby from the front for adjustably connecting the upper portions oi the trames to the lower portions thereof at the splits. 5

2. Spectacles including lens trames split at their inner sides, a bridge having end shields joined to the respective frames below the splits and extending upwardly above the splits, lugs extending from each of the frames above and below 10 the splits in back of the bridge, and means :loining said lugs i'or adju-stably connecting them, seid shields constituting means for concealing the lugs and connecting means when viewed from the front.

3. Spectacles including lens kframes split at their inner sides, upper and lower lugs extending from the respective ends of each frame at the split therein. means adjustably connecting said lugs to contract the frames, a bridge connected to each trame below the split area, and shields carried by the base for extending upwardly past the splits and lugs and the adjusting means.

4. Spectacles including lens frames split at their inner sides, nose pieces and a bridge joined to the frames below the splits, lugs extending from each frame above and below the splits therein. means connecting the lugs for adjustably connecting them to contract the frame without changing the relation between the nose pieces and the bridge. there being shields at the ends oi.' the bridge extending in front oi' and adapted to conceal the lugs and adjusting means and the splits.
